Downfall

The AMD Ryzen 7 5800X3D paired with the AMD Radeon RX 6600 delivers a playable experience in Downfall, though the balance between the two components shifts dramatically depending on resolution and quality preset. The data shows a clear pattern: at 1080p, the CPU’s strengths are fully exposed, while at 4K, the GPU becomes the definitive bottleneck. This analysis breaks down the measured FPS rows, contextualizes the hardware’s capabilities against its nearest rivals, and provides actionable settings guidance based strictly on the benchmark results.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5800X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer, manufactured on a 7 nm process. It operates with a base clock of 3.40 GHz and a boost clock of 4.50 GHz, with a 105 W TDP. Its defining feature is the large 96 MB shared L3 cache, which is critical for gaming workloads that repeatedly access the same data. The CPU’s benchmark scores reflect its balanced design: a Cinebench R23 multicore score of 14317 and a single-core score of 1452, alongside a Geekbench multicore score of 11765 and a single-core score of 2017.

In Downfall, a horror title that relies on consistent frame times, the CPU’s role becomes evident when examining the FPS at lower resolutions. At 1920x1080 with Low settings, the combo achieves 175 FPS average, which is the highest measured result across all configurations. This suggests that at 1080p, the CPU is able to feed the GPU sufficiently, and the frame rate is not artificially capped by processor limitations. The 3DMark scores reinforce this: a single-thread score of 884 and a max-threads score of 7285 indicate robust multi-threading that can handle the game’s background tasks without stuttering. The CPU’s percentile ranking against all processors is 80, placing it well above the median, and its nearest rivals include the Intel Core i9-10900K (0.1% faster) and the AMD Ryzen AI 5 PRO 340 (0.1% faster). This proximity in average benchmark scores—27896 for the 5800X3D versus 27887 for the 6800U—suggests that the CPU is not the limiting factor in most scenarios, but rather a capable foundation that scales well with the GPU’s output.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture, featuring the Navi 23 chip with 1792 shading units, 112 texture mapping units, and 64 render output units. It has 8 GB of GDDR6 memory on a 128-bit bus, delivering a bandwidth of 224.0 GB/s. The GPU’s clocks are notable: a base of 1626 MHz, a boost of 2491 MHz, and a game clock of 2044 MHz. Its compute capabilities are rated at 8.928 TFLOPS for FP32, which is adequate for 1080p and 1440p gaming but becomes strained at higher resolutions.

The GPU’s influence on Downfall is most apparent in the 3840x2160 results. At Ultra settings, the average FPS drops to 33, which is a significant decline from the 1080p Ultra figure of 73 FPS. This halving of performance when scaling from 1080p to 4K at the same preset indicates that the GPU is the primary bottleneck at higher resolutions, as the CPU’s workload does not increase proportionally with pixel count. The RX 6600’s percentile ranking against all GPUs is 63, and its nearest rivals include the NVIDIA Quadro K6000 (0% delta) and the NVIDIA GeForce RTX 4050 Mobile (0.1% faster). The GPU’s average benchmark score of 19036 places it in the mid-range tier, which aligns with the observed FPS—it can handle the game at high settings in 1080p (117 FPS) and 1440p (84 FPS), but struggles to maintain fluidity at 4K Ultra. The 8 GB VRAM is sufficient for the game’s textures at 1080p and 1440p, but the data suggests that at 4K, the GPU’s raw compute power, rather than memory capacity, is the limiting factor.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern across resolutions. Starting at 1920x1080 with High settings, the combo achieves 117 FPS. Moving to 2560x1440 High, the average drops to 84 FPS, a 28% reduction. At 3840x2160 High, the average falls to 52 FPS, which is a 56% reduction from the 1080p baseline. This scaling is consistent with a GPU-bound scenario, where the CPU’s performance headroom is not exhausted until the GPU is fully saturated.

The Low settings preset shows a similar trend but with higher absolute numbers: 175 FPS at 1080p, 125 FPS at 1440p, and 78 FPS at 4K. The percentage drop from 1080p to 4K is 55%, which is nearly identical to the High preset’s drop. This consistency indicates that the frame rate is primarily dictated by the GPU’s pixel throughput, not by the CPU’s ability to process game logic. In contrast, the Ultra preset exhibits the largest absolute drop: 73 FPS at 1080p, 52 FPS at 1440p, and 33 FPS at 4K, representing a 55% decline from 1080p to 4K as well. The fact that the relative scaling is uniform across presets suggests that the CPU is not introducing a bottleneck at any resolution; instead, the GPU’s rendering load scales linearly with resolution, and the RX 6600’s 224.0 GB/s bandwidth and 8.928 TFLOPS compute are the limiting factors at 4K.

The Medium preset data provides additional insight, as it includes min and max FPS values. At 1080p Medium, the average is 143 FPS with a min of 122 and max of 164. At 1440p Medium, the average is 102 FPS with a min of 87 and max of 117. At 4K Medium, the average is 64 FPS with a min of 54 and max of 73. The narrow min-to-max range at each resolution—roughly 30% of the average—indicates stable frame pacing, which is crucial for a horror game where sudden frame drops can ruin immersion. The data shows that the limiting component shifts from the GPU at higher resolutions to a more balanced workload at 1080p, where the CPU’s 8 cores and 16 threads can fully utilize the GPU’s capabilities.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal preset depends on the target resolution and desired frame rate. For 1080p gaming, the High preset delivers 117 FPS, which is well above the 60 FPS threshold for smooth gameplay. The Ultra preset at 1080p yields 73 FPS, which is still playable but offers diminishing returns for the performance cost. The Low preset at 1080p reaches 175 FPS, but this comes at a visual quality loss that is unnecessary given the High preset’s excellent frame rate. Therefore, for 1080p, the High preset is recommended as it balances visual fidelity with a high average FPS.

At 1440p, the High preset produces 84 FPS, which is adequate for most players, but the Medium preset provides a more comfortable margin at 102 FPS with a min of 87 FPS. Given the horror genre’s need for consistent frame pacing, the Medium preset at 1440p is the better choice, as the min FPS of 87 ensures no noticeable stutters. The Ultra preset at 1440p drops to 52 FPS, which is below the ideal threshold for fast-paced action, although it may be acceptable for slower exploration. At 4K, the data shows that only the Low preset achieves a playable frame rate of 78 FPS, while the Medium preset falls to 64 FPS, which is borderline. The High preset at 4K yields 52 FPS, and the Ultra preset drops to 33 FPS, making both unsuitable for a smooth experience. For 4K, the Low preset is the only viable option, but players should consider lowering the resolution to 1440p Medium for a better balance.

The Medium preset stands out as the most consistent across all resolutions, with a min FPS that is consistently above 60% of the average. For example, at 1440p Medium, the min of 87 FPS is 85% of the average of 102, indicating stable performance. This consistency makes Medium the recommended preset for players who prioritize smoothness over maximum visual detail, particularly at higher resolutions.
